I have these giant White scales under my foreskin there like a centimeter long and I haven't cleaned under my foreskin in 13 years please help
What you are seeing is called smegma. It is normal, harmless, and something that you should not worry about.
Now that you can retract you foreskin, you may wash it away. If it is hardened, then you may soften it with olive oil.
